6. Scope of MFI-5 (1/3) Objective
Provide a metamodel to register process models, including business process model, web service and so on.
Focus on the relationship between process model described with different process description languages, especially the composite process consists of sub-processes expressed in different languages.
Promote semantic interoperation between various process models.
Support process integration within/across organizations

11. Base Model (1/2)
Base Model is proposed to register structure information of various process models
Goal: the purpose that should be achieved by fulfilling the process model
Artifact: the resources that participate in the process, which can be carried by its Inputs or Outputs
Atomic Process: the process model characterized with the smallest granularity and one-step execution
Composite Process: the complicated process model which is composed of at least two sub-processes.

12. Base Model (1/2)

13. Process Control Model (1/3)
Process Control Model is defined to record two kinds of control constraints in process models
Artifact_Constraint
Added to Artifact
From registration info of ontologies based on MFI-3
Can be used to
establish a semantic bridge between different Artifacts
support input/output matching between different process models
Semantically annotate specified Artifact
avoid semantic confliction during process integration

14. Process Control Model (2/3)
Control_Constraint
Added to Process
Consists of
The conditions that should be satisfied before or after execution of the process model
The sequence followed by the sub-processes
Specially the conditions carried by control constructs, which are used to connect the sub-processes.

17. Research Progress on
Publish a paper named “A Metamodel for Enabling a Service Oriented Architecture” with Baba Piprani in ORM workshop 2008.

18. ORM schema of MFI-5 With Baba Piprani
From “A Metamodel for Enabling a Service Oriented Architecture”, ORM workshop 2008

19. Validation of MFI-5 Improve metamodels in MFI-5 2nd WD
Modify ORM schema accordingly
Validate MFI-5 in real projects
A RGPS-based process modeling tool has been developed
This tool is now being applied into urban transportation domain.
It is feasible to use RGPS-based process models as examples to validate MFI-5.
